摘要:

中、下侏罗统煤系为准噶尔盆地天然气藏的主要源岩,砂岩体、断层及不整合面为主要通道,三工河组上部和八道河组上部泥岩为区域盖层.以古气势为依据,盆地内可以划分出若干个运聚系统:莫索湾-石西运聚系统可以寻找到中低丰度的天然气聚集;石河子-呼图壁运聚系统可能有重大发现;滴西-阜康运聚系统中,除彩南地区已发现三工河组气田外,阜康东北地区亦是另一有利区;小拐-车排子运聚系统、玛湖运聚系统则难以形成大的天然气聚集.准噶尔盆地侏罗系主要存在原生和残余次生两大类4小类油气藏.

Abstract:

Middle-Lower Jurassic coal measures are the main source rocks of gas pools in Junggar Basin; sand bodies, faults and uncomfomities are migration pathways; the upper parts of Sangonghe and Badaohe Formations are regional cover rocks. Several hydrocarbon migration-accumulation systems could be divided within the basin such as Mosowan-Shixi migration-accumulation system containing gas pools of middle-lower abundance; Shihezi-Hutubi migration-accumulation system in which important hydrocarbon discovery might be found; Dixi-Fukang system in which Saogonghe Formation Gasfield was discovered and northeast Fukang region may be another favourable area; Xiaoguai-Chepaizi and Mahe systems which are less favourable for gas accumulation. In summary, two types of primary and residual secondary gas pools including 4 subtypes were found in Jurassic System in Jurassic Basin.

Key words: Middle-Lower Jurassic, coal measures, gas pool, migration-accumulation system, Junggar Basin
